I would support a fork of the coin to allow GPU mining to continue. I think it is more in the community spirit for a coin than to have it only mined by a handful of big companies.
It is interesting to go back on the launch threads of so many coins and see how they promoted decentralization and/or ASIC resistance, only for some amount time to pass then they don't seem to care anymore. Is it a case of the Dev's getting rich and really not caring, or are they being offered something in return for not forking? Big money always seems to corrupt things.
